# Helper function to add preprocesor definition of __MSIM_FILENAME__ to pass
# the filename without directory path and a longest extension for
# debugging use.
#
# Example:
#
#   define_filename_for_sources(my_target)
#
# Will add -D__MSIM_FILENAME__="filename" for each source file depended on
# by my_target, where filename is the name of the file.
